Scala Reactive Programming

By: Rambabu Posa

Overview of this book

Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala. You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud. By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka.

Introduction to RxScala

Nowadays, developing an application is not that much easier by following old design principles, design patterns, architectures, and technologies. We should develop our new systems to do the following things:

  • Our system should support today's multicore processor architecture
  • Our system should support Multicluster, Distributed, and Cloud environments
  • Our system should support today's big data environments
  • Our system should support very quick response to customer requests
  • Our system should support high traffic or a huge amount of users; that is, it should support heavy loads
  • Our system should be available all the time
  • Our system should utilize resources effectively

A Reactive system supports all these features easily. In this book, a Reactive system means developing our system or application by following the Reactive Manifesto principles.

A Reactive...
